摘要
水分胁迫使解放钟及长红３号两枇杷品种叶片光合色素含量下降，Ｃｈｌｂ比Ｃｈｌａ和Ｃａｒ更易受到伤害；气孔导度、光合及蒸腾作用受到抑制，光补偿点上升，光饱和点下降，对光合的抑制作用，既有气孔因素，也有非气孔因素。
Experiment was conducted with grafted plants of two loqaut varieties(Jiefangzhong andChang hong No. 3). Under water stress condition, the content of photosynthetic pigments in theleaves reduced, chlorophyll b was damaged easier than chlorophll a or carotenoid ; light compensation piont increased, while light saturation reduced; stomatal conductance, transpiration and netphotosynthesis rate (Pn) were restrained, Pn was induced by both stomatal factors and non-stom-atal factors.
